⚙️ Technical Architecture

Graph System

Force Configuration

// Navigation System
{
  radialForce: {
    strength: 0.8,
    radius: 180
  },
  collisionForce: {
    strength: 1.5,
    padding: 80
  }
}

// Content System
{
  charge: scaledBySize(),
  collision: dynamicPadding(),
  radial: voteWeighted()
}

Layout Management

• Separate force systems for navigation and content
• Dynamic force scaling based on node states
• Smart collision detection and prevention
• Position caching and smooth transitions
• Vote-weighted positioning for definitions
